try this:

  iwconfig wlan0

shows you signal strength. If it's 0/0, you're not connecting.

So try this:

  iwlist wlan0 scan

to show you a list of APs to connect to.

Maybe that doesn't work. So do this:

  iwconfig wlan0 ap any
  iwconfig wlan0 essid moylan-net
  
and scan again, and see if you get a decent signal strength.
